Our approval role

A cost pass through event is one that occurs beyond the reasonable control of a network business and has not been accounted for in its current 5-year revenue determination.

Examples can include new statutory obligations imposed on the business or extensive damage to infrastructure caused by a natural disaster.

They can occur at any time during a regulatory control period.

Under the National Electricity Rules, network business can submit a cost pass through application to the AER to recover its efficient costs incurred by the event.

We undertake a rigorous assessment of the application and make a cost-recovery determination based on the principle that consumers should pay no more than necessary for safe and reliable energy.

Historical cost pass through decisions are archived and are available by emailing AERinquiryataer [dot] gov [dot] au (aerinquiry[at]aer[dot]gov[dot]au).
